Mount Polley operations have been suspended, and as of May 31, 2019, the mine is on care & maintenance status. A resumption of operations is anticipated once the economics of mining at Mount Polley improve.
Extensive remediation work in the areas affected by the 2014 breach has been achieved during the past five years. The mine’s closure will not impact the ongoing environmental monitoring and remediation programs.
A four hole diamond drill program was completed in 2018 totalling 953.12 metres. The holes were drilled in the Saddle area between the Springer and Cariboo pits to confirm mineralization in this area for future mining plans. An exploration program to target the mineralization underneath the Saddle zone, separating the Cariboo and Springer Phase 6 pits, has been planned. During the period when mine operations are suspended, this is an opportunity to locate additional low stripping ratio reserves. A program of ground magnetometer surveying (2018) will be followed up in conjunction with targeted areas of soil sampling, prospecting and geological mapping. Future additional diamond drilling of targets in the vicinity of the Springer pit is being planned. The set exploration targets have been identified by a combination of soil sampling and geophysical surveys.
Mount Polley is an open pit copper/gold mine with an underground component located in south-central British Columbia, 56 kilometres northeast of Williams Lake. The property encompasses 20,113 hectares, comprised of seven mining leases totalling 2,007 hectares, and 46 mineral claims encompassing 18,106 hectares.
